python使用socket远程连接错误处理方法

本文实例讲述了python使用socket远程连接错误处理方法。分享给大家供大家参考。具体如下：

import socket, sys
host = sys.argv[1]
textport = sys.argv[2]
filename = sys.argv[3]
try:
 s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
except socket.error, e:
 print "Strange error creating socket: ％s" ％ e
 sys.exit(1)
try:
 port = int(textport)
except ValueError:
 print "Couldn't find your port: ％s" ％ e
 sys.exit(1)
try:
 s.connect((host, port))
except socket.gaierror, e:
 print "Address-related error connecting to server: ％s" ％ e
 sys.exit(1)
except socket.error, e:
 print "Connection error: ％s" ％ e
 sys.exit(1)
try:
 s.sendall("GET ％s HTTP/1.0\r\n\r\n" ％ filename)
except socket.error, e:
 print "Error sending data: ％s" ％ e
 sys.exit(1)
while 1:
 try:
   buf = s.recv(2048)
 except socket.error, e:
   print "Error receiving data: ％s" ％ e
   sys.exit(1)
 if not len(buf):
   break
 sys.stdout.write(buf)

希望本文所述对大家的Python程序设计有所帮助。
